Have to learn how to use it. Definitely ask on the forum if you're having performance troubles so you can find some tricks to use or request improvements. -There are two measurement tools in the [time](../spec/system.md#time) system values. `•MonoTime` is a high-precision timer for performance measurements; you can take a time before and after some operation or section of a program and subtract them to get a time in seconds (a profiling tool to do this automatically would be nice, but we don't have one). More convenient for small snippets, `•_timed` returns the time to evaluate `𝔽𝕩`, averaging over `𝕨` runs if given. For two argument functions you can write `w⊸F•_timed x` or `F´•_timed w‿x`. CBQN also has a `)time` command that prints the time taken by an entire expression, not counting compilation time. +There are two measurement tools in the [time](../spec/system.md#time) system values. `•MonoTime` is a high-precision timer for performance measurements; you can take a time before and after some operation or section of a program and subtract them to get a time in seconds (a profiling tool to do this automatically would be nice, but we don't have one).
